If you haven't filed your taxes in two, three, five, or even more years, you may be wondering: Where do I even start?

For many people, one missed tax return turns into another. Before long, several years have passed, IRS letters may have started arriving, and the thought of getting caught up can feel overwhelming.

The good news is that ignoring the problem isn't your only option. There is a process for getting back into tax compliance, even when multiple years of returns haven't been filed. The key is figuring out what needs to be filed, what information the IRS already has, and what should happen first.

Why Do People Fall Behind on Their Taxes?

There are many reasons someone may have unfiled tax returns. You may have:

  • Started a business or become self-employed and didn't understand the filing requirements.
  • Been missing W-2s, 1099s, or other tax documents.
  • Experienced financial difficulties.
  • Filed an extension but never completed the return.
  • Believed you couldn't file because you didn't have the money to pay.
  • Gone through a major life event and taxes simply fell behind.
  • Missed one year and then became overwhelmed as additional years accumulated.

Whatever caused the problem, the important question now is: What do you need to do to move forward?

First: Filing and Paying Are Two Different Issues

One of the biggest misconceptions I hear is: "I can't file because I can't afford to pay what I owe."

You generally don't have to wait until you have enough money to pay the entire balance before addressing an unfiled return. Filing the required return and paying the resulting tax balance are separate parts of the process.

Depending on your circumstances, there may be payment options available after the returns are filed and the actual amount owed is determined. Continuing not to file simply because you believe you'll owe money can make an already difficult situation more complicated.

How Many Years Do You Need to File?

This is where professional review can be important. You shouldn't automatically assume that you need to prepare every tax return you've missed without first determining your filing requirements.

The IRS generally focuses on taxpayers becoming current with required returns, but the exact filing requirements can depend on the taxpayer's circumstances and IRS compliance procedures.

There may also be situations where an older return still matters because of an IRS notice, existing balance, substitute return, business issue, state requirement, or another tax matter. Before preparing years of returns, determine which tax periods actually need attention.

What If You Don't Have Your Old Tax Documents?

Missing documents are common when someone hasn't filed in several years. Maybe you moved. Maybe an employer closed. Maybe you can't find an old W-2 or 1099.

That doesn't necessarily mean you're stuck. IRS transcripts may provide information about income documents that were reported under your Social Security number or taxpayer identification number. Depending on the situation, these records may help identify items such as:

  • W-2 wages
  • 1099 income
  • Retirement distributions
  • Interest income
  • Certain other information returns

However, IRS records don't necessarily contain everything needed to accurately prepare a tax return. For example, if you operated a business, you may still need to reconstruct your income and legitimate business expenses using records such as bank statements, receipts, invoices, merchant processor reports, mileage records, and other documentation.

What Happens If the IRS Files a Return for You?

This is something many taxpayers don't realize can happen. If you are required to file and don't, the IRS may eventually use information available to it to determine a tax liability. This is commonly associated with what is called a Substitute for Return, or SFR.

An IRS-prepared substitute return isn't the same as you preparing and filing an accurate return using all of the information you're entitled to report. That's one reason IRS notices shouldn't simply be ignored. If the IRS has already taken action on an unfiled year, your strategy may be different from someone who simply needs to prepare several late returns.

What About Penalties and Interest?

If you owe tax on a late return, penalties and interest may apply. The amount depends on the circumstances, including how late the return is, the amount owed, and other factors.

This is another reason to address unfiled returns sooner rather than later. Once the returns are prepared, you'll have a clearer picture of what you actually owe, what penalties have been assessed, what years are involved, and what options may be available next. In some circumstances, taxpayers may qualify for certain types of penalty relief, but eligibility depends on the facts of the case.

What If You're Due a Refund?

This is another reason not to wait indefinitely. There is generally a limited period for claiming a federal tax refund. That means someone who is afraid to file because they think they owe money could actually discover that one or more unfiled years would have produced a refund.

But if too much time passes, the ability to receive an older refund may be lost. Being behind doesn't always mean you owe the IRS. You need the returns prepared to know where you actually stand.

A Better Way to Approach Multiple Unfiled Returns

If you're several years behind, don't begin by randomly preparing returns. Start by understanding the entire situation. A good catch-up process may include:

Step 1: Identify the missing tax years

Determine which returns were filed and which weren't.

Step 2: Review available IRS information

Account and income transcripts can help establish what the IRS has on record.

Step 3: Gather your records

Collect W-2s, 1099s, bank statements, business records, dependent information, and other documents needed for each year.

Step 4: Reconstruct missing information when necessary

Business owners and self-employed taxpayers may need additional work to accurately reconstruct income and expenses.

Step 5: Prepare the required returns

Each year should be prepared based on the tax laws and information applicable to that particular year.

Step 6: Determine the total situation

Only after the returns are prepared can you clearly see whether you're dealing with refunds, balances due, penalties, or a combination of all three.

Step 7: Address the balance

If you owe and can't pay the entire amount immediately, the next step is determining what payment or collection options may be appropriate for your situation.

Don't Let Fear Keep Adding Years to the Problem

If you're already several years behind, another year won't make the situation easier. You don't need to know exactly what forms you need. You don't need to calculate what you owe before asking for help. And you don't need to have every document perfectly organized before taking the first step.

You simply need to start.
